Hi J.P. No, before the execution the number of iteration is not known. However the iteration number is known just right before rendering the subgraph. So in programming language paradigm it is the same as for-loop with known number of iterations.
In the future one can think on iterating until some criteria is reached, which is not that easy with osg. One can overcome this by placing some kind of draw callback which don't stop iterating until some criteria. cheers, art J.P.
